Monitor just goes off after a short time

I have a Emprex LM- 1704 TFT LCD Monitor which just goes blank after a short time running. However if I power off/on it will restart but again go off after aprox 2mins. when it is working the picture is perfect, This seems to have started after being switched off for a week while I was on holiday.
I have tried to take the unit apart but although I've taken every screw in sight out it still does not come apart easily & seems prone to breaking if I try to force it
can you please offer any help or at least point me in the right direction to an answer ?

all those sounding intelligent and saying that replacing lcd hardware will fix the problem probably didnt have the problem themseleves . i had exactly same problem with samsung syncmaster 2043swx monitor . i just restarted and booted into safe mode ( by pressing F8 key at startup ) tried changing reolution in display settings . rebooted in normal mode and asll lines are gone and never appear again . i am uisng windows Vista . so i think it is probably a driver glitch something .

Isolate the problem per above. Eliminate the monitor, split cable and software settings so that each, individually work. Then eliminate team board - do you have a spare?It could mean sharing the monitor signal means weakens it so that one can display and the other does not work. Prove it with a different source computer. Don't know if buffer devices exist or how to increase input sensitivity.

Contact the store that sold it to you.
It may still be under warranty.
If not, then the internal power-supply has "popped".
It's probably cheaper to replace the whole monitor than it would be to repair/replace the power-supply.

If this has an internal power supply (no external brick) then you probably have failure of the capacitors inside. The problems exhibited by these failures are usually summed up as "works for a short while and quits" or "will not come on". Yours is probably similar to some Gateway monitors that I have repaired, The parts required for the repair should be under $10.00 and should take under an hour. Now you need to find a shop that can and will do the work unless you have soldering skills.
